by using the formula for arithmetic sequence, the 16th term of the progression can be obtained. Given A1 = 8 and d = 3,

A16=A1 + (n-1) d

A16=8 + (16-1) (3)

A16 = 53

I hope I helped! Be safe!

Answer:

53

Step-by-step explanation:

We know the first term and common difference so we can write the explicit formula. The formula is:

aₙ = a₁ + (n - 1)d

aₙ = 8 + (n - 1) * 3

aₙ = 3n + 5

This means that a₁₆ = 3 * 16 + 5 = 53

Help pleaseeeeee!!?’dndjfjcjdc
Vanyuwa [196]

answer: 50°

If triangle is isosceles than L and J are same angles

3x + 20 = 4x + 10

3x-4x=10-20

-x = -10 (divide both sides by -1)

x=10

angle L=J = 3*10+20= 50

we can calculate it like this too 4*10 +10= 50

Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given curves
zubka84 [21]
When integrating using shells, the first step is to plot the graph. I personally plotted it with the x and y axis switched, because it aids me in picturing the graph. The integral ranges from 9 to 11, since those are the limits from the two lines y = 9 and y = 11. The reason that these are the limits is because it is rotating around the x, not the y.
\int\limits^{11}_{9}
Now that you have the limits of the integral, you have to find what goes inside it. 
Because you are integrating using shells, you need to remember to include the 2\pi y Again, there is a y here instead of an x, because you are rotating around the x axis. Then you just need to input the function f(y). If you look at the graph that you (hopefully) plotted, you can see that this function ranges between the y axis and the curve f(y) = \frac{9}{y}. Put together the pieces, and you have the integral
\int\limits^{11}_{9} {2 \pi y*f(y)} \, dy
After substituting in f(y) = \frac{9}{y}, you get 
\int\limits^{11}_{9} {2 \pi y*\frac{9}{y}} \, dy
Simplified, this is 18\pi\int\limits^{11}_{9} \, dy
Integrating, we get 18\pi * 2

Therefore, the solution is 36 \pi

Note: I didn't spend very much time reviewing these integrals, so I may be incorrect.

Ozzie Foster deposits $2,000 at the end of each year (ordinary annuity) into an Individual Retirement Account at Bishop Bank. Th
myrzilka [38]

The ordinary annuity and annuity due as required in the task content are; $126,498.08 and $135, 431.43 respectively.

<h3>What is the annuity due?</h3>

a) The amount which would be in the account in 25 years can be evaluated by means of the annuity factor obtained from the table under column 7% and row 25 years and hence, the value in 25 years would be; $2,000 × 63.24904

= $126,498.08.

b) For the annuity due case; the future value is;

= (1+0.07) × $2000((1+0.07)^(25) - 1)/0.07

= (1.07) × $2000(5.43-1)/0.07

= $135, 431.43.

F(x)=x^2-3x+18 what is the value of discriminante of f?
vlada-n [284]

Answer:

- 63

Step-by-step explanation:

f(x) = 1x² - 3x + 18

a =1, b= -3, c=18

D= b² - 4ac = (-3)² - 4*1*18 = - 63
